JQuery :: Changing The Id Of A Form That Calls A Function?
Nov 21, 2011There is a line in a jquery plugin that I am using that calls a function to run on the inputs of form "autoSubmit."
Code:
$(function(){
$('#autoSubmit INPUT').autoSubmit();
});
My problem lies in that I have multiple of these forms on a single page, each one named autoSubmit. I easily rename each with PHP to autoSubmitXXX or YYY depending on their record id numbers, but then the .autoSubmit(); function doesn't know which form to work with.
Code:
'#autoSubmit INPUT'
I can grab the individual form ID (XXX or YYY) with:
Code:
var where_val = form.find('#where').val();

JQuery :: Timing Not Quite Right - Hide() Function Calls Immediately Without Waiting For The Animate() Function To Run
Apr 1, 2010I'm using jQuery 1.4 to hide a div (#cartPop) when the "close" link inside of it (#cartPop a) is clicked. Since I'm using animate() to fade the div out (opacity), I also have to use hide() to get rid of the div once it has faded out (otherwise the invisible div, which is on a higher z-index, blocks the elements on a lower z-index).
Code:
The problem is that the hide() function calls immediately without waiting for the animate() function to run. Even if I append a delay() function before hide() like so:
Code:
...it still doesn't wait.
Function, The Creation Of Select Calls Another Function CliK(sel.id)?

JQuery :: Triggers Ajax Calls On Button Click?

View 1 Replies View RelatedJQuery :: Prevent Multiple AJAX Calls From Button/link Push?
Sep 28, 2010I am working on a project that relies heavily on AJAX calls, they are done in dozens of places. There are a number of places where I would want to prevent the user from submitting information multiple times (form submissions etc ). I am trying to think of the best way to accomplish this.
I could simply disable the element that starts the AJAX call upon the first click and re-enable it upon completion of the call. I have also seen examples of developers using a class to handle ajax calls that store an identifier for the call and if it is in progress any new calls with the same identifier will be ignored.

View 7 Replies View RelatedMaintaining State Between Function Calls
Jul 23, 2005I would like to add dynamic text sizing to a website. There will be three text sizes. When the default is used, only the "Increase text size" button is shown. When the maximum size is used, only the "Decrease text size" button is shown. And otherwise, both buttons are shown.
I've been working on a mockup as follows at the end, but my issue is that once I have manipulated an element of the HTML DOM, if I access it again to check it's value, I will only get the original value in the document. To do the dynamic buttons, I need to maintain some kind of state between function calls, so that I know what the current size is. Can I even do this with Javascript or am I barking up the wrong tree?
Adjusting Function For Multiple Calls?
Oct 17, 2010I have a search function which works when I only want to have only one search per page, but as it involves a string call I'm not sure how to modify it to multiple search requests on a page.
The below works fine for one call:
<script type="text/javascript">
function showHint(str){
if (str.length==0){
[code]...
The above doesn't work and I am not sure what do about the showHint(str) as clearly I am not representing it properly in my attempt to modify the script.
Javascript Object Function Calls
Mar 7, 2006I am creating a JavaScript object which I want to use to respond to user input on a web page. The object will basically be made up of a constructor and then a selection of functions which will use the DOM to alter the appearance of the page according to the user's input. I am getting stuck because I want a form element that is being created by the object to have an 'onkeyup' event attached to it which will call another function from the same object.
Now, I understand how to attach the 'onkeyup' event to the input element I have created using the DOM. If I tell the event to call a normal function (alert() etc) then it does exactly that. What I am having trouble with is getting the event to call another function from the object that created the input box in the first place. (I don't even know if this is possible / a wise thing to do!). Code:
Two Calls For The Same Window Function, But One Fails?
Aug 16, 2011Two calls, one from a form and one from the html body reach the same 'window.open' function but only the former works.
The idea behind the simplified script of my post is to select to open one of two windows (files) by pressing one of two buttons. Each button passes a different parameter to the 'open/focus' window function. This function has an argument(arg) place holder to determine which window(file) to open(or focus) when a button is pushed and a corresponding string(argument) is passed. The window function is simply a double function,repeating the same if-else statements. That is, with the function(arg): "if(if-else) else(if-else)", the argument passed to 'arg' will determine if[to] {open else focus file1(button1)} else[to] {open else focus file2(button2)} in a new window.
Using a PC with either Explorer or Firefox, both the form button and the button coded in the html body opened a new window, but only the form button could bring the window forward(via 'object.focus') if it was already open. Using a Mac with Firefox, the form button worked well either to open or to bring forward an existing window, but the the button coded in the html body did nothing. Two 'alert' are place in the window function to show that the html button's call is reaching the window function. My question is that if this call from the html button passes through the same statements as that of the form button, why does it fail? (The script is in Perl, but it can be viewed as html in the source page.)
PHP Code:
#!/usr/bin/perl -w
use CGI qw(:standard);use CGI::Carp qw(fatalsToBrowser);use strict;
my $query = new CGI;
my $JSCRIPT=<<EOF;

HTML Link That Calls Function?
Jun 14, 2010I am currently trying to make an html link that will add elements (specifically, drop down menus) to the current page when you click it. Since I am adding all the elements to the page using JavaScript, I'm not sure how to set up the link to call a function rather than go to a different page. I've seen people set the href attribute to the function they want, so I tried that and it didn't work. I've also seen a way that involves using onclick and making the link follow the onclick, not go to a different page.
In summary, how do you create/edit a link (from javascript) to make it use a javascript function rather than go to a different page? This is what I have currently (that concerns the link):
var link = document.createElement('a');
eval("link.setAttribute('href', 'javascript:addHours(" + dayDiv + ")');");

Multiple Function Calls From A Single Js File
Dec 11, 2007i have 4 images that expand onMouseOver and shrink onMouseOut
<script src = 'js/size.js'>
<div id = 'img1' onMouseOver = "expand(this.id)" onMouseOut = "shrink(this.id)">
<img src = ...>
</div>
<div id = 'img2' onMouseOver = "expand(this.id)" onMouseOut = "shrink(this.id)">
<img src = ...>
</div>
etc...
question: when i quickly move the mouse from one image to the other shouldn't i see one expand and one shrink simultaneously? i am currently seeing one shrink, then the other expand after. on occasion the shrink is skipped and the next image is expanded right away.

JQuery :: Using .ajaxError And Passing Error Function In Ajax Calls?
Jun 25, 2010I'm currently rewriting all my ajax calls to use the jquery method (much cleaner code! ) and have declared a default ajaxError function, shown below:
$(document).ajaxError(function(event, request, settings){
alert("There was an error while communicating with the server. URL: " + settings.url);
});
However, now I have a few ajax calls where I want to declare an error function in the ajax call. I was hoping that by declaring an error function in the ajax call, it would replace the default error call I have defined. But that does not appear to be the case, as I continue to first get my ajax function error call, then I also see the above code execute.
I tried calling event.stopImmediatePropagation() from within my ajax error function hoping that it would stop further events firing (ie: the default error event) but that didn't do anything except tell me in firefox that "event" was undefined.
I was hoping I wouldn't have to go through and define an error function to EVERY ajax call.

For Loop - Execute Function() When Submit Button Within Form Has Been Pressed?
Oct 18, 2009[Code]...
1. What is the benifit of having the above code with "window.onload" and "for loop" and loop through the forms if I only have ONE form in html?
2. What is this line of code "document.forms[i].onsubmit" saying? Does it mean "Execute function() when submit button within form[i] has been pressed?"
3. function() - Does this empty function mean "run every following function below"??
